Yeah, that came with the used 9500+G3 that i got. I'm not sure what
original equipment card is. It's probably a great card for gamers
and graphics hackers, but it doesn't appear to be very close to the
'Twin Turbo' card that we have a driver for. Among other things,
its frame buffer is +0x20 bytes from where our driver expects it
and fixing that offset isn't sufficient, as it still doesn't update
things properly in text-only mode. X Windows doesn't seem much
happier with it, either.

I've tried both X 4.0 and X 3.x on it, with little success. It
only works as an OpenFirmware display. Worse yet, MacOS/OF loves
to reset it when booting doesn't go well, so i have to boot into
MacOS to reset the screen resolution. As an 'OF only' display,
it doesn't seem to matter which kernel one runs, they're all
equally bad...

It will run under X, but you have to make sure that at least the
screen depth matches whatever MacOS/OpenFirmware has last set it
to. And you're stuck with whatever screen resolution you've booted
with, you can't reset it dynamically. So be careful with your font
path (in terms of 100 bpi vs 75 bpi fonts) to make things readable
given your own monitor and eye sight.

My recollection is you'll need "video=ofonly", which BootX will set
for you if you select the "no video driver" checkbox.

P.S. If you're a Debian user, let's take the discussion to their
general LINUX PowerPC mailing list, where it will be more on-topic.
